Description
Technical Field
The invention relates to the field of construction of outer walls of building deep foundation pits, in particular to a construction method of an integrated structure of the outer walls of a foundation-pillar-free deep foundation pit.
Background
In the traditional construction process, as shown in figure 3, a template support is erected, a waterproof coiled material is laid on a cushion layer, a basement structure bottom plate 12 is poured on the waterproof coiled material, an outer wall side line is bounced on the cushion layer, a constructional column 30 is erected on the inner boundary and the outer boundary of the outer wall, then a template wall for pouring an outer wall 15 is fixed based on the constructional column 30, a template enclosing wall is removed, finally, the outer side 31 of the basement outer wall continues to extend upwards along the wall surface to cover a waterproof roll layer, and the constructional column between the basement outer wall and the foundation pit supporting side wall is removed, and backfilling earthwork.
Therefore, in the existing construction of the basement exterior wall of the deep foundation pit shown in fig. 3, the exterior wall template and the inner side constructional column close to the center of the foundation pit cannot be backfilled between the exterior wall template and the foundation pit supporting side wall, so that the waterproof layer cannot be paved, and the basement exterior wall is subjected to water seepage.
Therefore, in the support design stage, a certain operation space, namely 1.2m-1.5m, is ensured, the design width can be convenient for installing formwork enclosing walls on the inner side and the outer side of the outer wall sideline in a wide place, the distance between the inner side formwork enclosing wall and the outer side formwork enclosing wall is controlled by using the opposite-pulling screw rods, and the wide place is also convenient for the evacuation of constructors. If the deviation appears when receiving place restriction or lateral wall fender pile construction, the operation space will reduce, and the actual construction also can often have the operation face of actual reservation and reduce a lot than the operation face of design reservation, so construction condition is very unfavorable to above-mentioned outer wall construction method construction this moment, finally causes very negative effect to engineering quality and construction safety.
On the other hand, in the existing outer wall construction process, firstly, the reserved space between the supporting pile and the outer wall of the basement is too large, so that the earthwork excavation and the backfill amount are directly increased, and the construction cost is increased; secondly, the working procedures are more, the lapping of the front working procedure and the rear working procedure is limited and is influenced by narrow space, so that the working efficiency is not high, and the adverse effect is generated on the construction of a basement; thirdly, the backfill construction of the outer wall is difficult, and the backfill cost is high.
Disclosure of Invention
Based on the actual problems, the technical scheme provided by the invention can provide the wall body for supporting the waterproof coiled material, the wall body can form an enclosing wall for pouring the basement outer wall by pulling the formwork, and can resist extrusion of backfill materials to the wall body when the wall body is backfilled between the basement outer wall and the foundation pit supporting side wall, so that the displacement of the waterproof coiled material layer is avoided, the space between the wall body and the foundation pit supporting side wall can be backfilled before the basement outer wall is poured, and the working procedure of constructing the supporting columns on the side, facing the foundation pit supporting side, of the wall body and the working procedure of recovering the supporting columns are omitted. Therefore, dependence on the outer space in basement exterior wall construction is reduced, namely the outer space can be controlled within 0.5m, meanwhile, construction period and cost are saved, the foundation pit is designed into an integrated structure of the outer wall more flexibly and more economically, the efficiency of deep foundation pit basement exterior wall construction is improved, the whole construction progress is accelerated, and the construction cost of the foundation pit is reduced.
According to the technical scheme, the construction method of the foundation-pillar-free type deep foundation pit outer wall integrated structure can improve the construction efficiency of the deep foundation pit basement outer wall, greatly quickens the overall construction progress compared with the traditional basement outer wall construction, and can reduce the construction cost of the foundation pit.
In order to solve the technical problems, the invention adopts the following technical scheme:
a construction method for an integrated structure of an external wall of a foundation-pillar-free deep foundation pit comprises the following steps:
and 6, pouring an outer wall between the enclosing wall and the inner side tire membrane retaining wall.
Preferably, in the method, the step (2) is replaced by laying waterproof rolls along the cushion layer, the annular groove, the outer side membrane retaining wall and one side of the ring beam facing the inside of the foundation pit, wherein each adjacent waterproof roll is staggered;
a step is added between the step (4) and the step (5): and (4) continuously building the outer side tire membrane retaining wall and the inner side tire membrane retaining wall above each layer of ring beam according to the methods in the steps (1) to (4), laying waterproof coiled materials, filling high-strength mortar, and backfilling plain concrete until the elevation is reached.
The invention has the beneficial effects that:
1. the requirement on the outer construction operation surface is small, the earth excavation amount is reduced, and the construction is flexible; the whole supporting system is designed to be close to the outer wall of the basement, so that the period for building the outer wall formwork of the basement is shortened, constructional columns are omitted, and the earthwork construction amount and the outer wall backfill amount are reduced.
2. The tie bar installed on the foundation pit supporting side wall fastens and connects each layer of ring beam with the foundation pit supporting side wall through the connecting bar, the ring beam fixes the outer side fetal membrane retaining wall and the inner side fetal membrane retaining wall, and prevents the falling of the outer side fetal membrane retaining wall and the inner side fetal membrane retaining wall when plain concrete is backfilled, thereby avoiding the displacement of the waterproof coiled material laid between the outer side fetal membrane retaining wall and the inner side fetal membrane retaining wall, and the inner side fetal membrane retaining wall is pulled and tied with the template through the pulling and hooking ring and the pulling and tying screw rod, thereby ensuring the flatness of the outer wall poured between the inner side fetal membrane retaining wall and the template, on the other hand, directly backfilling the plain concrete between the outer side fetal membrane retaining wall and the foundation pit supporting side wall, and omitting the construction quantity of the supporting structure of the outer side fetal membrane retaining wall, thereby shortening the construction period of the basement outer wall.
In general, realize deep basal pit basement outer wall integral type construction, not only can practice thrift construction period greatly, can let the foundation ditch design more nimble more practice thrift moreover.
